Yeah, taking backup now. This is happening since 6th, and never happened. No Errors thrown. After data backup, first should I try to DEL the partition and create it again?

in a command prompt use >chkntfs C: to observe if the dirty bit itself is set, and >chkdsk.exe C: /f to do the "deeper" scanning. I think that the chkdsk that occurs at startup (when needed) is the lightweight setting of it, and does not always "fix" everything. a Common way to fix this was to do the next level up of chkdsk with the F parameter. I Comment here because as dave pointed out at any rate a person would want to backup thier data anyways. Lots of people "fixed" this with a full chkdsk, doesnt mean it will fix it for you though.

I've SOLVED this problem. First, I took ~20 GB data backup to other drives. Then did a quick check in the Registry for autocheck autochk * entries. Nothing unusual I've found. So before installing SeaTools, I want to test my own trick. DELETED the 25 GB NTFS D: partition. Created it again. Reboot the PC. Voila, no more CHKDSK!! I'm happy and relieved. Thanks all for the tricks. No CHKDSK entries found in Event logger (Winlogon entry).
